Weight gain is a potential side effect of anastrozole, particularly during the first year of treatment. Several factors can increase your risk of significant weight gain, including:
• Being under age 60
• Having had a mastectomy
• Smoking cigarettes
Many MyBCTeam members have shared similar experiences with weight challenges while on this medication. Some have reported gaining anywhere from 10 to 35 pounds despite maintaining regular exercise routines. Here are practical tips to help manage your weight while taking anastrozole:
• Track your food intake using a notebook or phone photos
• Limit alcohol consumption
• Start with light exercise and gradually increase activity
• Consider working with a registered dietitian
• Keep a consistent exercise routine - even moderate activity 6 days per week can help
Remember to always consult with your healthcare provider before starting any new weight management plan.
